基于谐响应分析的振动试验仿真计算方法研究

Research on simulation calculation method of vibration test based on harmonic response analysis

本文介绍谐响应分析的基本理论,结合谐响应理论解释扫频试验和定频试验的原理。以中国船级社的振动试验参数为试验条件,研究试验参数条件统一化处理方法、扫频试验和定频试验的仿真分析方法。最后,以LC滤波器为对象,进行了仿真分析及优化设计。

This paper introduces the basic theory of harmonic response analysis,and explains the principle of sweep frequency test and constant frequency test combined with harmonic response theory.Then,by taking the vibration test parameters of China Classification Society as the test conditions,this paper studies the unified processing method of test parameters and conditions,which is used to the simulation analysis method of sweep frequency test and constant frequency test.Finally,this paper takes a LC filter as an example,and carries out the simulation calculation and optimization design.
